Product Technology and Advantages:

ROSCHEN manufacturing drilling tools, is a leading brand in Germany, China, and the DTH Hammers without foot-valve are the most popular products in particular.

Compared with the DTH Hammers of the same specification with foot-valve, the advantages of DTH Hammers without foot-valve are as follows:

1. Higher impact frequency and faster drilling speed, with the speed being 15%-20% higher than the ones with foot-valve;

2. Lower air consumption and lower oil consumption, with 10% of the oil consumption saved;

3. Avoid the trouble of foot-valve fracture and expand when heated, or the contraction when cooled;

4. Fewer internal parts, simple in structure, long in service life, and easy to assemble and disassemble. The new type hammer has been well received by users since its launch. Hammering tests have been carried out on the hardest iron ore mine in China.

Compared with the products from Halco and ATLAS COPCO, the new type fast hammer produced by our company is about 10% faster in terms of speed. Besides, since the thickness of the external cylinder of the hammer from our company is increased, its service life is longer than others. As to bits, the quality of products provided by our company is comparable to those from the above mentioned two companies; in the meantime, the cost performance of drilling tools branded ROSCHEN is much higher than those branded Halco and ATLAS COPCO.

Roschen group limited is a refractory metal manufacturer specializing in the raw material and deep-processing product of tungsten, molybdenum, tantalum, niobium, rhenium and tungsten carbide.

• We have conquered the technological difficulties in welding between the tungsten carbide wear-resistant material and stainless steel-based and iron-based. The geometrical tolerance of weldment can be controlled in level A.

• Relying on powder metallurgy institute and engineering materials institute of Central South University, We have established a production-learning-research base to provide powerful technologic support for products reserch development. And we have the whole production equipment from mixing to finish machining, including the world’s most advanced cold isostatic pressing machine which can manufacture the widest and longest plate.

• Our over 200 technicians, 10 after-sales personnel and 120 manufacturing workers are all heartedly at your service.

The Chracteristics of high pressure series DTH hammer:

Deliver maximum energy to drilling bit, which enables fast drilling speed and low air consumption due to the special inner structure of the DTH hammer series designed according to newest rock drilling theory. Deliver smooth performance and long service life of the DTH hammer series due to the high quality tungsten carbide steel materials and the advanced processing technology. Low problem rate and easy maintenance due to the simple, reliable and easy assemble and disassemble inner structure of hammer.
